source: CurrencyManager

CurrencyManager del DataGrid que contiene la columna.

rowNum: Int32

El número de la fila en la tabla de datos subyacentes.

alignToRight: Boolean

Valor que indica si se va a alinear a la derecha el contenido de la columna. Es true si el contenido debe alinearse a la derecha; en caso contrario, es false.

Comentarios

El Paint método usa GetColumnValueAtRow para determinar el valor que se va a dibujar en la celda. Se PaintText llama al método para dibujar la celda y su contenido.
